IMIPROVEMENT IN STUMP-EXTRACTORS.

To all whom t may concern.-

Be it known that I, THOMAS J .BROWN, of Belvidere, in the county ofBoone, and State of Illinois, have invented an Improved Stump-Machine;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and letters marked thereon, making a part of this description,in which- Figure l is aperspective representation of my invention inposition for use.

Figure 2, a longitudinal sectional elevation of the central bed-piece,drum, and lever.

The `nature of the present invention consists in ar. ranging the drum toturn on a vertical shaft, and operate in combination with a lever andratchet-stops, the latter passing through the lever, and being arrangedto fall into notches in the top of the drum, by their own weight, as thelever is moved backward, thus obviating the necessity for raising thelever, when it is turned back to catch another notch, or raising it,when the rope or chain is to be paid out from the drinn to reach astump; and, further, in supporting the lever, when the machine is movingfrom place to-place, by the same wheel which supports 'it when themachine is inv operation; the whole being operated in combination withsheave-blocks, pulleys, chains, 85o., as hereinafter shown. Y

A A represent the runners or sills of the machine, which are made ofwood, and bolted fast to abedpiece or centre-block, B, which is castaround a shaft, H, and thus holds it in place. V

This shaftis made of wrought-iron, and sufficiently strong to withstandany strain to which it maybe sub-1 jected, by means ofl the chain f,wound around the drum E, and a Shoulder is formed on it at the top ofthe drum, to support a washer, V, fig. 2, on which a lever, L, bears.The upper' end of the shaft passing through the lever, holds it inplace.

On the lower part of the periphery of the drum are made notches, J, onwhich a spring pawl, K, (attached to the sill A,) falls, and holds whatchain .the drum has taken up, in the usual manner; and on the top of thedrum are made a series of notches, F F, in which rate chet-stops, G G,catch, and move the drum when the lever L is turned.

These stops t loosely in, the mortises made in the lever L, and areraised over the inclined surfaces of the-notches F, by the backwardmovement of the lever, and drop into the notches by their ownqweight.

By this arrangement of the ratchet-stops, lever, and drum, the operatoris enabled to pull a stump where there is but little travelling-room,and also pay out the chain f to reach another stump without carrying thelever backward, as is the case when the lever L -is made fast to thedrum.

The outer end'of the lever L is supported by awheel,

-N in the ordinary manner, but provision is made, by

means of an axle-arm, M, iig. 1, to place the wheel N in position totravel with the machine when it is being moved from place to place.

P, iig. 1, represents a sheave-block, which is pivoted to the end of thebed-piece B, by means of lugsfO O and holt d, and arranged to swing andadjust itself to the position of the stump to bc removed. Thisan'angement is important, and prevents the chain from drawing off fromthe pulleys R R;

Another sheave-block, T, is used, in combination with the block P,simply to multiply leverage.

Upe'rction.

Fasten-the anchor-chain W to a stump or stake, Y, as shown at fig. l,then remove the yratchet-stops G G, and carry the chain U over the stumpto be removed, and fasten it in the usual manner. The stops G G are thenreplaced, and the lever' L moved by horsepower, or otherwise, in thedirection indicated by the dart as.

Having thus fully described my invention,

" What I claim, and desire to secure by Letters Pat ent of the UnitedStates, isl- The combination and arrangement of the drum E,

sills A, lever L, arm M, stops G, centre-block B, shaft H, sheave-blocksT P, and wheel N, substantially as and for the purpose set forth. g
